The, means; 36, best shown inEIGURES 5 and 6, is provided for, effecting return of the actuatingmeans upon completion. of asing le cycle.

Themachine of -the present invention also comprises: adjustment means 38for, varying the positioning, of the, data: vehicle in its receivingmeans so as to vary the, punchingfield on the vehicle Looking now atFIGURES 2, 3, 4 and; 11, it will be seen that the machine, 1 0includes abase 4,0.ehaving side, wall portions at 4; and 44 providing bearingsandfixed; supports for the various, components of the, machine. Thereceiving means 1;2 and,14 for the data template. and; data; vehicle,respectively, includethe topchute 46,

and the plurality of plates 48, 50, 52, 54, 56, 58 and 60. The plates48, 50, 52 and 54 are provided with upper openings at 62, 63, 64 and 65so as to provide access for the roller means 18 to be described indetail hereinafter. as at 66 which correspond with the columns ofpunches 68, there being ten columns of nine punches each. The plate 50is formed with individual apertures corresponding with the size andshape of the individual punches 70 so as to cooperate therewith forpunching openings in the data vehicle inserted in the receiving means14. The plate 52 may be of generally U-shape or made up of a pair ofsections which act as spacers defining the thickness of the slot at 72for the data vehicle. The plate 54 has an upper opening at 74corresponding with the opening '62 and 64, and is also open at 76 so asto permit passage of the punches 70 therethrough. The plate 56 actssimilarly to the plate 52 so as to provide a slot 78 for the datatemplate. The plate 58 corresponds with the plate 48 and has verticalslots at 80 corresponding with the columns of punches 68. Finally, theplate 60 has the multiplicity of apertures 82 formed thereincorresponding with the apertures 51 in the plate 50 for guidinglyreceiving the individual punches 70 therethrough. FIGURE 6 shows thesuggested construction of the plate 56 with the slot 78 extendingtherethrough. Four pins pass through aligned apertures as at 84 forsecuring the assembly of plates 48 through 60 to the frame side wallportions 42 and 44, the pins having spacer elements at 86 forpredeterminedly positioning the receiving means with respect to theupstanding walls 42 and 44.

Guide means for the individual punches 70 comprises the pair of spacedguide plate assemblies at 88 and 90. The guide plate assembly 88includes the pair of plates 58 and 60 and the guide plate assembly 90includes the heavy plate 92 with oversized openings 94 therethroughreceiving the individual punches, with the second plate 96 held againstthe plate 92 and formed with apertures 98 therein closely correspondingin size and shape to that of the punches 70. Thus, the plates 60 and 96at all times have spaced portions of the punches 70 guidingly receivedtherethrough for positive support thereof.

The plate assembly 90 is held in spaced relation to the plate assembly88 by means of the spacer bar at 100. A pin at each side extendstherethrough to hold the assembly with the enlarged annuli at 102. Thespaced guide plate assemblies are also held in fixed parallelrelationship by means of the above described pins 83.

The punching means 16 includes a punch carriage comprised of a firstplate assembly 104 and a second plate assembly 106. The first plateassembly 104 includes a pair of plates 108 and 110 having a series ofvertical slots at 112 and 114 corresponding with the columns of punches68 and receiving the punches 70 therethrough. The plate assembly 104includes a thin plate 116 on one side of the pair of plates 108 and 110and a second thin plate 118 on the other side of the pair of plates 108and 110. Bolts or screws such as the bolts 120 connect the pair ofblocks 122 formed with slots at 126 at one side of the plates 108 and110 for slidably supporting the thin plate 118. The blocks 124 areprovided with slots, as at 128, for the thin plate 116 but the width ofthe slot is such that when the blocks 124 have been clamped to theplates 108 and 110, the thin plate 116 is fixedly held thereby. As shownin FIGURE 3, the plate assembly 104 receives the multiplicity of punches70 therethrough and thereafter the plate 116 is laterally slid so as toengage in one of the slots of each of the punches 70 as will bedescribed in fm'ther detail.

Reference is now made to FIGURES 3, 8, 9, and 10. 'Iheslidable plate 118constitutes a locking plate and is moved in response to operation of thepunch carriage withrespect to the receiving means. One end of the plate,118 has a pin 132 outstanding therefrom. Another pin 134is fixed to theplate 108 and has the bight por- The plate 48 is formed with a set ofvertical slots tion of a generally V-shaped spring 136 engaged thereon,with one leg of the spring coiled about the pin 132 of the plate 118.The plate 110 has an L-shaped bracket 138 secured thereto, as by ascrew, and a bell crank 140 is pivotally mounted on the horizontalportion of the bracket 138. One leg 142 of the bell crank 140 is engagedthrough aligned openings in the plates 108 and 110 and terminates in anapertured portion which receives the other leg of the spring 136therethrough, so that upon pivoting of the bell crank 140, motion istransmitted to the slidable plate 188 to move the same from its firstrelationship, see FIGURE 8, to its locking relationship as shown inFIGURE 9.

The bracket 144 is secured to the spacer bar 100 at one side of themachine. The bracket 144 has a terminal portion 146 extending inwardlyso as to be positioned adjacent the other leg 148 of the bell crank 140.A leaf spring 150 is secured to the bracket 144 as at 152 and has itsend portion engaging the opposite side of the leg 148 of the bell crank140. Thus, as the punch carriage 16 is moved to the left in carrying thepunches through the receiving means, the leg 148 of the bell crank 140engages the portion 146 of the bracket 144 thereby pivoting the bellcrank pulling the leg 142 of the bell crank laterally. Such movement ofthe bell crank leg 142 effects sliding movement of the plate 118 throughthe resilient spring 136. Because the movement is transmitted throughthe spring 136, it will be seen that the rectangular cross-sectionterminating at one end in a slight bevel at 154 to provide a cuttingend. Each punch 70 is provided with a pair of notches 156 and 158 with ashoulder 160'therebetween. The notch 158 has another shoulder at 162. Inassembling the punch carriage, the plate 116 is positioned so as toengage the shoulders 162 of the notches 158 of the punches so that thespring pressed punches are held thcreagainst while the plate 118 isnormally out of engagement with the punches as shown inFIGURES 8 and 9.

The second plate assembly 106 includes a pair of relatively thinchannel-shaped plates 164 and 166 held in spaced relation by the spacersleeves 168 and connected together by rivets 170 through the sleeves168. A plurality of plungers 172, corresponding in number to the punches70, are engaged through the spaced plates 164 and 166 so as to be guidedinto engagement with the rear ends 174 of the punches 70. Each plunger172 is formed with an annulus as at 176 which limits outward movement ofthe plungers in one direction, and springs 178 are engaged between theannulus 176 and the plate 166 so as to normally urge the plungersagainst the punches 70 and resiliently limit movement of the plungers inan opposite direction.

The operating means for effecting reciprocation of the punch carriage 16includes the means 24 at each side of the machine. Means 24 comprises apair of elongated links 180 passing through slots 182 in the side barsor blocks and the various plates connected thereto with end portions ofthe links terminating in apertured connectors 184. The plates 108 and110 of the punch carriage 16 include lateral slots 186 opening out atthe sides and receivin the apertured connectors 184 thereinto. Each ofthe slots 186 has a block 188 received therein with flange portions 190extendingbeyond the slots so as to be engaged over portions of theplates 108 'Vefsely extending pin1-94 extending toward the oppositeside' and engaged in the aperture of the connector end :of the links180. In this fashion, the links 180 are pivotally connected to the punchcarriage 16 and can effect reciprocatiori of the latter. r

w The. opposing ends of the links 180 are formed with enlargedapertures196 Whichreceive. the eccentric cams 198 therein. The eccentric cams 198are fixed to the main shaft 200 for rotation therewith so that uponrotation of the shaft 200, and the eccentric cams 198, the links 180 arereciprocated a predetermined amount for proper movement of the puncheson the punch carriage 16.

The main shaft 200 has itsends extending through the side plates 42 and44 of the frame, there being bearing bushings provided therefor as at202. i

The roller printing means 18 includes a roller 204 which is adapted tobe vertically reciprocated as seen in FIG- URES 3 and 4 so as to beengaged through the openings 62, 63, 64 and 65 in the plates 48, 50, 52and 54 of the receiving means whereby the roller 204 can be directlyengaged against the data vehicle received in the slot 72 to press thesame against the raised printing of a data template received in the slot78 of the receiving means 1-2. The roller 204 is rotatably carried onthe upper end of the links 206 which extend downwardly and have theirlower ends pivotally carried by the shaft 208. The links 206 have camfollowers 210 rotatably carried thereby adjacent the printing rollers204. A pair of cam elements 212 are vertically disposed so as to providecam surfaces at 214 cooperative with each of the rollers or camfollowers 210. The cam plates 212 are secured to the upstanding sidewalls 42 and 44 of the frame, as by thescrews 216 and 218. The camplates 212 can have their relationship to the receiving means 12 and 14adjusted by means of the adjustment screws 220 and 222 which are engagedagainst the back side of the plates 212. The ad justment screws 220 and222 are threadedly engaged through the blocks 224 which in turn aresecured to the side walls of the frame. The screws 216 and 218 permitsuch adjustment, as will be obvious. The cam plate 212 is also providedwith the roller at 226 which serves as a guide roller for a carbon stripto pass over as will be describedin greater detail hereinafter.

The portion of the operating means 26 which transmits reciprocatingmotion to the roller means 18 from the main shaft 200 comprises a pairof generally U-shaped forks 228 which have their bight portions fixed tothe transverse shaft 230, which in turn has its ends rotatably mountedin the bearings 232 in the frame side walls 42 and 44. The forks 228 arespaced from the side walls 42 and 44 by means of the spacers 234 whichare also pinned to the shaft 230. One leg of each of the fork members228 is formed with an aperture, as at 236, the apertures being alignedand receiving the shaft 208 therethrough so as to pivotally connect thelinks 206 at each side of the machine to the respective forks 228. Theshaft 200 has a pair of eccentrics 238 fixedly secured thereto forrotation therewith between the legs 240 and 242 of each of the forks228. It will thus be seen that as the main shaft 200 is rotated, theeccentric 238 will similarly be rotated, and by engagement with theinside surfaces of the legs 240 and 242 of the forks 228, the latterwill be pivoted on the shaft 230 and will transmit verticalrepicrocatory motion to the links 206 through the shaft 208 whereby theroller 204 is moved upwardly and downwardly over a preselected portionof the receiving means.

The carbon roll means 20 includes a replaceable roll of carbon in stripform at 244. FIGURES 2, and 11 show the mounting for the carbon roll244. The side Wall 42 of the frame has a bearing portion 246 receiving apair of bushings 248 and 250 therein, each of the latter havingperipheral portions as at 252 and 254 which engage opposite surfaces ofthe bearing portion 246. Stub shaft 256 is rotatably supported withinthe bushings 248 and 250 and is, formed with an enlarged annulus at 2586 engaging'the inside surface of the bushing 250 to prevent outwardmovement of the shaft 256. The outer end of the shaft 256 is formed witha threaded portion 260 on which is engaged a nut 262. A spring 264 isengaged between the pair of washers 266 and 268 whereby upon adjustmentof the nut 262, predetermined drag is placed on the shaft 256. Thus, asthe carbon strip is removed from the carbon roll 244, the carbon rollwill not override in consequence of the intermittent drawing of thecarbon strip "through the machine.

A second shaft 270 has one end thereof externally threaded, as at272, soas to be threadedly engaged into a threaded recess at 274 at the insideend of the shaft 256. The shaft 270 has an enlarged annulus receivedthereon at 276 and the shaft 256 is provided with a similar formation at278 whereby the core of the carbon roll 244 having a bore therethroughat 280 can be received on the shaft 270 with end portions thereofengaged between the enlarged annu-li at 276 and 278. The knurled not 282on the outside end of the shaft 270 is internally threaded so as to beadjustable onthe shaft 270 and has the formation 276 integral therewithfor clamping the carbon roll 244 between the annuli 276 and 278.

When it is desired to replace the carbon roll 244, rotation of theknurled end 282 will disengage the threaded end 272 of the shaft 270from the first shaft 256 so that the entire carbon roll and shaft 270can be removed and a new roll placed thereon.

The carbon strip 284 passes from the carbon roll 244 upwardly over theroller 226 carried by the cam plate 212 above described and then passesover the curved portion 286 of the plate 288 extending from the roller226 so as to feed the carbon strip 284 across the opening 62 of thereceiving means 14. The carbon strip traverses downwardly over theroller 204 of the roller means 18 and then rearwardly through the carbonroll feed means 22 now to be described.

The carbon strip feeding and holding means 22 includes the first andsecond roller assemblies 290 and 292 respectively. The roller assembly290 includes a transversely extending shaft 294 having a pair ofenlarged knurled portions at 296 and 298 for frictional engagement withthe carbon strip. The ends of the shaft 294 are rotatably receivedwihtin the eccentric bushings 300 and 302 which are engaged through thealigned bores 304 and 306. The eccentric bushings 300 and 302 can berotated so as to vary the positioning of the knurled portions 296 and298 with respect to the second roller assembly 292 and then theeccentric bushings can be locked in their adjusted positions by means ofthe set screws at 308 and 310.

The second roller assembly 292 includes a pair of transversely spacedrolls of rubber, rubber-like material, or other suitable material forgripping the carbon strip against the knurled portions 296 and 298' anddrawing the same through the machine. The rubber-like rolls are shown at312 and 314 as being carried on spaced hubs 316 and 318, respectively,carried on the bushings 320 and 322. A stub shaft 324 extends betweenthe hubs 316 and 318 and is fixedly connected to the same so as to becoupled for movement therewith. The outer ends of the hubs 316 and 318are rotatably received on the bearing bushings 320 and 322 which in turnare supported by the transverse shaft 326. The shaft 326 is mounted inthe side walls 42 and 44 of the frame and held from rotation andtransverse movement by means of the set screw at 328. The stub shaft 324is of hollow construction and is freely rotatable anound the fixedtransverse shaft 326. The hubs 316 and 318 have knurled annular feedrings 330 and 332 fixed thereto by the set screws 334. The feed rings330 and 332 may be used for rotating the rolls 312 and 314 by hand whenso desired.

The portion on the operating means 26 which functions to cause feedingand holding rotation of the roller means 292 will now be described. Thehollow shaft 324 has a hold ratchet 336 fixedly secured thereto, as by apin, for rotation therewith between the pair of rolls 312 and 314. Asecond feed ratchet 338 is also fixedly secured to the hollow shaft asby a pin. A holding pawl 340 has oneend thereof at 342 freely carried onthe bushing 344 which in turn is fixed to the transverse shaft 230, asby a pin. The bushing 344 has an outstanding pin 346 thereon forretaining one end 348 of the coil spring 350. The other leg 352 of thespring 350 has an angulated portion 354 engaged over the holding pawl340 for normally resiliently urging the same against the hold ratchet336 The other end of the holding pawl 340 has a configuration at 356which conforms to the peripheral shape of the hold ratchet 336 so as tofunction to resiliently hold the ratchet 336 from rotation, and,therefore, hold the carbon strip feeding means from rotation. The feedratchet 338 has a feed pawl 358 cooperative therewith. The feed pawl 358has one leg 360 adapted to engage the teeth 362 of the feed ratchet 338.The pawl 358 is pivotally mounted on the lever 364 by means of the pin366. The lever 364 in turn is fixed to the shaft 230 as by a key or pinfor rotation therewith at 368. The bushing 370 on the shaft 230 has acoil spring 372 carried thereby with one leg of the spring 374 engagedagainst the pin 376 on the lever 364. The other leg Of the spring at 378is engaged against the pin 380 on the leg 382 of the pawl 358 remotefrom the ratchet end at 360.

It will thus be seen that as the shaft 230 is rocked by the action ofthe fork 228 in consequence of rotation of the main shaft 200, the lever364 will be pivoted first downwardly as the fork 228 moves upwardly. Thepawl 358 will move from the position shown in FIGURE 3 and will pivot inopposition to the action of the spring leg 378 so as to clear theratchet 338. Upon movement of the fork 228 downwardly, the lever 364will be moved upwardly again and during the end portion of its movement,the pawl portion 260 will engage a tooth 362 of the ratchet 338 rotatingthe same a predetermined amount counterclockwise so as to effectrotation of the rubber or rubber-like rollers 312 and 314 which are heldagainst the knurled portions 296 and 298 whereby the carbon strip 284therebetween is drawn along the path shown in FIGURES 3 and 4 throughthe machine. It will be noted that the movement of the carbon strip 284is correlated to movement of the roller 204 so that movement of thecarbon strip occurs only during the latter portion of the complete cycleof movement of the roller 204 when it is finally released from pressingcont-act against the carbon strip and the data vehicle held in thereceiving means 14.

The means for efiecting rotation of the main shaft 200 will now bedescribed. Motor means is provided at 28, as shown in FIGURES 5 and 11,and includes a substantially conventional electric motor 384 which isconnected to a gear reduction box 386. A sprocket 388 at the driven endof the gear reduction box 386 has a chain 390 connected thereto fordriving sprocket 392 which is freely rotatably received on the mainshaft 200. The ratchet 394 is fixedly connected to the sprocket 392through the spacer 396 for coupled rotation relative to the shaft 200. Acam plate or clutch element 398 is fixedly secured to the shaft 200 asby the pin 400 through the hub 402 of the cam plate 398. The cam plate398 is of generally circular shape but is formed with a generally radialshoulder at 404, as seen in FIG- URE 7. A ratchet pawl 406 is pivotallycarried by the cam plate 398 on a pin at 408 with one leg of the pawl406 having a shoulder formation at 410 adapted to engage the teeth 412of the ratchet 394. The latter leg of the pawl 406 has a tension spring414 connected thereto as at 416, the other end of the spring beingconnected to the pin 418 on the cam plate so asto normally resilientlyurge. the pawl 406 intogengagement with the teeth 412 of the ratchet.The other leg 420 of the pawl 406 is in juxtaposition to the shoulder404 and provides a surface formation at 422 which is slightly leadingthe shoulder 404. 1

As best seen in FIGURES 5 and 7, the cam plate 398 has a cam pawl 24cooperative therewith, the pawl being pivoted on the pin 426 rotatablycarried by the frame wall portion 42. The cam pawl 424 has the endportion 430 thereof formed with a shoulder at 432 which opposes thesurface 422 of the ratchet pawl 406 and the shoulder at 404. The portion430 of the cam pawl 424 is provided with a cam follower at 434. Theopposing end of the pawl 424 has an extension 436 which is adapted toengage the finger 438 of the micro-switch 440, so that upon pivoting ofthe cam pawl 424 the micro-switch is actuated to start operation of themotor 244. It is to be noted that the cam pawl 424 must move downwardlyto effect operation of the micro-switch and; therefore, the motor 244.

The cam operating element 442 is fixedly mounted for movement with thecam plate and therefore the main shaft 200 and includes a cam surface at444 which is beveled slightly at the entrance end 446. The surface 444,446 is cooperative with the roller 434 of the cam pawl 424.

Pivoting the cam pawl 424 is effected in a manner to be describedpresently. Upon proper insertion of the data template and the datavehicle, as will be described hereinafter, the cam pawl 424 isdownwardly pivoted about the pin 426 so as to simultaneously actuate themicro-switch 440 and pull the surface 432 from engagement with theshoulder 404 of the cam plate and the surface 422 of the ratchet pawl406. Such operation permits rotation of the cam plate and allows thespring 414 to pull the ratchet pawl 406 into engagement with the ratchetteeth 412. Thus, rotation of the sprocket 392 is coupled with rotationof the ratchet and, through the ratchet pawl 406, transmits rotarymotion to the cam plate. The cam plate being fixedly secured to the mainshaft 200 causes rotation thereof through one complete cycle.

As viewed in [FIGURES 5 and 7, the cam plate and the main shaft 200 willrotate clockwise through a complete revolution and during the latterportion of such revolution, the roller 434 will be engaged against thecam surfaces 446 and 444 successively to thereby draw the cam pawl 424upwardly to a position opposing the shoulder 404 and ratchet pawlsurfaces 422. Inasmuch as the surface portion 422 leads the shoulder404, the cam pawl 424 will first engage the ratchet pawl so as todisengage it from the teeth 412 of the ratchet in opposition to theurging of the spring 414, thereby disconnecting the cam plate from theratchet on the shaft 200. The subsequent contact of the cam pawl 424with the cam plate shoulder positively stops rotation of the main shaft200 and therefore all of the operating means operated thereby.

FIGURE 12 shows a data template element 448 which is preferably formedof a relatively rigid plastic having a beveled corner at 450, raised orembossed printing at 452 and a plurality of coded perforations as at454. The perforations 454, of course, can be useful for identifyingpurposes. The slots 454 are of a size substantially corresponding to thepunches hereinabove described.

The template 448 is adapted to be inserted into the slot 78 of thereceiving means 12 formed by the generally U-shaped plate 56, thetemplate being inserted downwardly so as to seat against the lower endof the slot 78 defined by the edge 456 of the plate 56. When thetemplate 448 is properly inserted into the slot 78, the corner thereonat 458 will engage the pin 460 on the lever 462 to pivot the latter onpin 464. The detent or locking lever 466 which is pivoted on the pin468, as shown in Figure 6, has its lower end 470 connected to the lever462 by means of the link 472. The screw 474 is utilized for adjustingthe connection between the 9 pins 476 and 478 on the lower ends of thelevers 466 and 462, respectively. 'It will thus be seen that properinsertion of the template 448 will eifectpivoting of the lever 462coupled with pivoting of the lever 466 for a purpose to be described indetail hereinafter. 1;; The slot 72 of the vehicle receiving means 14 isadapted to receive a data vehicle such as an IBM type card, or otherform, such as an invoice form. A card is shown at 480 projectingupwardly from the vehicle receiving means. The data vehicle receivingslot 72 has a centrally disposed trigger finger 482 extending thereintoso as to be engaged by the template element when properly inserted intothe slot 72. -The trigger finger 482 is pivotally carried on thep-in 484which in turn is carried by the block 486. The latter is internallythreaded and carried by the center post 488. The trigger finger 482 andblock 486 are held from rotation by the fact that the upper end of thetrigger finger 482 is slidably held in a slot in the plates 50, 52 and54. The center post 488 has its upper end rotatably received in theangle iron bracket 490 secured to the guide plate 92 by the screw 492.The upper end of the center post- 488 is formed with an enlarged head at494 to limit downward movement thereof. Another angle iron bracket isprovided at 496 and is secured to the vertical plate 54. A coil springis proyidedat 498 for engagement against the washer 500 so as tonormally resiliently hold the center post '488 in its upper position.The washer at 502 is secured to the center post 488 for movementtherewith and limits the upward urging of the coil spring 498. The nut504 is a lock nut while the nut 506 is utilized for effecting rotationof the center post 488 for vertical adjustment of the position of thetrigger finger 482. The operating lever 508 is secured to the operatingshaft 510 by means of set screw 512 and has its free end downwardlymovable upon movement of the center post 488, the latter movement beingeffected by proper insertion of the data vehicle into its slot 72 andengagement with the trigger finger 482.

Looking at FIGURES 3 and '6, it will be seen that the detent portion 467of the lever 466 is, prior to insertion of the data template, engagedbeneath the enlarged end 494 of the center post 488 so as to preventdownward movement thereof. Thus, until a data template is properlyinserted, operation of the machine cannot be eifected.

In order to limit the insertion of the data vehicle into its respectiveslot, inasmuch as the trigger finger 482 is free to move downwardly to avariable extent, a pair of fixed stops are provided at 514 "and 516, theuppermost surfaces of these stops being disposed below the operative endof the trigger finger 482. The stops 514 and 516 are carried by thetransverse plate 518 and are also internally threaded so as to receivethe adjustment posts 520 and 522 therethrough. The connection betweenthe blocks 514, 516 and the transverse plate 518 is effected through thepins 524 and 526, there being a slot provided at 528 so that uponvertical adjustment of the screws :520 and 522, tilting of the plate 518is permitted.

A medial portion of the plate 518 has a struck-outportion at 530carrying the pivot pin 532. The transverse Wall 518 is formed with ashoulder at 534 which limits upward pivoting of the detent 536. A coilspring 538 is engaged on the pin 532 and has a leg portion 540 thereofengaged beneath the pin 542 of the detent 536 so as to normally hold thedetent in its up position against the shoulder 534. It will thus beobvious that as the trigger finger 482 is moved downwardly by insertionof an IBM type card, the center post 488 will be moved downwardlypivoting the lever 508 and the shaft 510 to which it is connected.Downward movement of the trigger finger 482 effects pivoting of thedetent 536 on its pivot 532 in opposition to the action of the spring538. Upon return of the center post 488 upwardly, the trigger fingerportion "at-544 engages the tip 546 of the detent 536 whereby the 1'0trigger finger is pivoted out of the slot of the receiving means 14. Inthis fashion, upon completion of a cycle, the return of the triggerfinger does not strike the IBM type card, and repeated operation of themachine is prevented since the trigger finger is out of its operativeposition.

The adjustment screws 520 and 522 have their upper ends rotatablyreceived in the brackets 548 as shown in FIGURE 3 and their lowerendsare engaged through the flanges 550 and 552 of the bracket 554 whichin turn is secured to the plate 54 by means of the screws 556.Adjustment screws 520 and 522 each have an annular ele ment 558 securedthereto as by a pin 560 to prevent downward movement of the screws. Eachscrew has a lock nut 5,62 threadedly engaged thereon. 'Thus, byloosening the lock nut 562 the adjustment screws 520 and [522 can berotated as by a screw driver engaged in the slots 564 and 566, wherebythe blocks 514 and 516 can be vertically adjusted in the data vehiclereceiving slotwln this fashion, the data vehicle, such as an IBM typecard, can have its position in its respective slot adjusted so that anyportion thereof can be disposed in the punching field of the series ofpunches 70, according to the need therefor. Of course, both the centerpost 488 and the adjustment screws 520 and 522 must be individuallyadjusted for determining the position on the punching field on the datavehicle or IBM type card.

The shaft 510 extends to oneside of the machine and has the plate 568secured thereto so as to be pivotal therewith. A link 570 has its upperend pinned to the cam pawl 424 by means of the pivot pin 572. The link570 is in two parts which are interconnected by means of the screws 574engaged through the slot 576, so that upon tightening the screws 574,the link 570 is substantially non-extensible. The purpose of the twopart construction of the link 570' is for adjustment only. The bracket554 has a pin 576 engaged through the slot 578 of the link 570 so as topermit vertical sliding movement of the link. The rear side of the link570' is formed with a spring retainer pin 580 which has the upper end ofthe spring 582 connected thereto, the lower end of the spring beingconnected to the fixed bracket 554 by pin 584. In this fashion, the link570 is normally resiliently urged to its down position. However, theplate 568 is normally in its vertical position retaining the pin 586 onits upper surface 588, the pin 586 being connected to the link 570 so asto support the latter in its upper position with the cam pawl 524engaged against its cooperative shoulder on the cam plate.

It will thus be seen that rotation of the shaft 510 effects pivoting ofthe plate 568 to a position shown in FIGURE 7 whereby the pin 588 isreleased for downward movement due to the urging of the spring 582whereby the link 570 pulls the cam pawl 424 downwardly actuating themicro-switch and starting operation of the motor through a completecycle.

Operation From the foregoing description of'the constructional detailsof the machine, it is believed that the operation will be apparent. Adata template such as the plastic card 448 is inserted into thereceiving means 12 so that the corner 458 thereof engages the pin orroller 460 pivoting the lever 460 and therefore the lever 466 as shownin FIGURE 6. This releases the upper end of the center post 488 fordownward movement when depressed. Next, a data vehicle, such as an IBMtype card, is inserted into its respective receiving means 14 so as toengage the upper end of the trigger finger 482, and with the properpressure applied to the data vehicle, the latter Will move downwardlyagainst the stops 514 and 51-6, and the resultant movement of thetrigger finger 482 will effect downward movement of the center post 488pivoting the lever 508 and thus the shaft 510. As above described,pivoting of the shaft 510 moves the plate 568 from its vertical positionto thetilted position shown in FIGURE 7, whereby the pin 586 is releasedfor downward movement due to the urging of the spring 582, and the campawl 424 is pivoted to the position shown. This actuates the microswitchwhich controls operation of the motor means 28. The motor drives thesprocket 388 through the gear reduction box 386. In turn, the sprocket392 is driven through the chain 390 for rotation relative to the mainshaft 200. The ratchet 394, being coupled to the sprocket 392, rotatestherewith. Because of downward pivoting of the cam pawl 424, the'ratchetpawl 406 is released to the action of the spring 414 so as to engage theteeth 412 of the ratchet 394 whereby a positive connection is madebetween the cam plate 398 and the ratchet 394 so as to initiate rotationof the cam plate 398.

Rotation of the main shaft 200 causes rotation of the cams or eccentrics198 fixed thereto so as to effect reciprocation of the links 180 whichcontrol operation of the punch carriage. As the punch carriage movesforwardly from the position shown in FIGURE 8 to the position shown inFIGURE 9, preselected of the punches 70' pass through the perforations454 of the template 448 while the remaining punches 70 have theirmovement obstructed by the template and are held back in opposition totheir spring pressed plungers 172, 178. As shown in FIGURE 9, the bellcrank 140 is pivoted at this point pulling the locking plate 118 intoposition behind the shoulders 160 so that continued movement of thepunch carriage forces the punches 70' through the data vehicle at 480.In this fashion, the data vehicle is punched correspondingly to the datatemplate 448.

Simultaneously with the movement of the punch carriage, the fork 228 ispivoted by the action of the cams or eccentrics 238 so as to effectvertical reciprocation of the roller means whereby the roller 204 ispassed through the opening 62 against the carbon strip therein so as topress the latter against the data vehicle 480 which in turn is pressedagainst the raised or embossed printing 452 on the template 448 so thatthe printed information is transferred to the data vehicle.

Pivoting of the fork 228 causes pivoting of the hold pawl 340 and thefeed pawl 358. Upward pivoting of the fork 228 forces the hold pawl 340against its respective ratchet to prevent rotation of the carbon stripfeed means. When the roller 204 is moving downwardly and has completedits printing operation, the feed pawl 358 moves upwardly during the lastportion of the pivoting of the shaft 230 and engages the ratchet teeth362 to effect rotation of the rubber or rubber-like rolls 312. Suchrotation draws the carbon strip 284 between the rubber or rubber-likerolls and the knurled portions 296 and 298. In this fashion, apredetermined amount of carbon strip is moved through the machine aftereach printing operation.

As the cam plate reaches the end of its complete cycle, the roller 434of the cam pawl 424 is engaged against the surfaces 446, 444 of the campawl 442 so as to pull the pawl 424 upwardly whereby it first engagesthe ratchet pawl 406 pivoting it out of contact with the ratchet teeth412, in opposition to the urging of the spring 414. Continued movementis stopped by engagement beween the shoulder 404 of the cam plateagainst the shoulder 432 of the cam pawl 424. The cam 442 also serves topull the link 570 upwardly against the urging of its spring 532 so as tolift the pin 586 above the upper end of the plate 568. Upon upwardmovement of the pin 586, the plate 568 returns to its vertical positionby the action of the spring 590, as shown in FIGURE 6. This rotates theshaft 510 back to its original position whereby the lever 508 is pivotedupwardly causing the center post 488 to move upwardly.

Upward movement of the center post 488 carries the trigger finger 482therewith but the shoulder 544 engages the tip 546 of the detent 536, asseen in FIGURE 3, so as to pivot the trigger finger 482 from the slot ofthe receiving means 14 until it reaches its uppermost position 'at whichtime it is released and pivots back towards the slot of the receivingmeans 14. In this fashion, the trigger finger 482 does not engage thebottom of the data vehicle in its respective slot but drops against theside thereof so that a repeat cycle is not possible, it being necessaryto first remove the data vehicle to release the trigger finger into thedata vehicle receiving slot.

In view of the foregoing, it is believed that we have fulfilled theobjects hereinbefore enumerated.
